Demanding girlfriend Kate Hudson

The How To Lose A Guy in 10 Days' actress and the New York Yankees baseball star split earlier this month and sources claim Alex, nicknamed A-Rod, had grown tired of Kate's behaviour when she went to watch him play.

One said: "Kate wanted more camera time each and every game. She would always want to be styled before games and she'd insist on front-row seats.

"It was a turn-off to have a girlfriend who always wanted to be on camera. Alex wanted someone who was more interested in building a long-term relationship than just building their profile."

Alex - who has two young daughters with ex-wife Cynthia - also felt smothered by mother-of-one Kate and wanted more freedom.

The source added to gossip blogger Perez Hilton: "He's just coming off of a 13-year relationship with his ex-wife and a recent divorce. He has two lovely children with his ex-wife, and that requires a certain amount of responsibility. She gave him ultimatums that a newly divorced father can't meet."
